Considering the netbook I got for this project is non-functional I have decided to look into building a smaller robot without the burden of the 2 lb netbook. This idea hit me when I stumbled across these servos. They weigh 9 grams and cost $3.50. Compared to what I was spending for the larger 55 gram HiTec servos, +/- $30, these are a steal. I went ahead and ordered a few to do some benchmarking. So far I am very impressed. I want to construct a leg and get a feel for accuracy before ordering more. With these prices this project may well produce a six legged walker from the start.
Here they are side by side:
